Petrel Sub-basin Marine Survey: Seabed Video and Images for CO2 Storage Assessment

May 2012 underwater video footage and 12-megapixel still images from 11 stations in the Petrel Sub-basin, collected by the RV Solander. The survey was a collaboration between the Australian Institute of Marine Science and Geoscience Australia under the National Low Emission Coal Initiative. Its purpose was to acquire biophysical data on shallow seabed environments to investigate CO2 storage potential.

Use Cases

• Classifying seabed habitats and biota based on underwater video footage.
• Assessing seabed geomorphology and substrate for CO2 storage site investigation using still images.
• Analyzing the distribution of marine life across 11 survey stations.
• Studying the quality and variability of underwater imagery from a towed-camera system.

Strengths

• Imagery includes 12-megapixel resolution still photographs.
• Data collection is linked to a specific survey (GA-0335 / SOL5463) with documented methodology.
• Files are systematically named by station, gear code, and deployment number for traceability.

Limitations

• Imagery quality varies among transects, and some still images were not suitable for analysis.
• No still images are available for stations 2, 4, and 7 due to system malfunction.
• Geo-location of video transects is approximate, linked only to ship navigation due to USBL system failure.
